The healthcare controller 130 may collect and calculate a biosignalmeasured through the biosignal measuring sensors 111 and 112. Thehealthcare controller 130 may be connected to the biosignal measuringsensors 111 and 112 through the selecting device 120 when measuring thebiosignal.

In this case, thevoltage controller 121 may control a second group of control signals CN3and CN4 to be in a deactivated state during the charging operation.

On the other hand, the voltage controller 121 may activate the secondgroup of control signals CN3 and CN4 to perform measurement operationwhen the voltages of the nodes A and B are less than the predeterminedspecific voltage. In this case, the voltage controller 121 may controlthe first group of control signals CN1 and CN2 to be in a deactivatedstate during the measurement operation.

The charge selecting device 122 may connect the biosignal measuringsensors 111 and 112 and the sensor device battery 140 according to thefirst group of control signals CN1 and CN2 during the chargingoperation. That is, when the first group of control signals CN1 and CN2are activated during the charging operation, the sensor device battery140 may be connected to the nodes A and B. In this case, the connectionsbetween the healthcare controller 130 and nodes A and B may be cut off.

When the first group of control signals CN1 and CN2 are activated duringthe charging operation, a charging path may be formed such that chargingcurrent flows to the sensor device battery 140 through the pogo pin 200,the biosignal measuring sensors 111 and 112, the nodes A and B, and thecharge selecting device 122.

The charge selecting device 122 may include switching elements T1 andT2. Here, the switching element T1 may be connected between the node Band the sensor device battery 140, so that switching operation may becontrolled in response to the control signal CN1. The switching elementT2 may be connected between the node A and the sensor device battery140, so that switching operation may be controlled in response to thecontrol signal CN2.

The sensor selecting device 123 may connect the biosignal measuringsensors 111 and 112 to the healthcare controller 130 according to thesecond group of control signals CN3 and CN4 during the biosignalmeasurement operation. That is, when the second group of control signalsCN3 and CN4 are activated during the measurement operation, thehealthcare controller 130 may be connected to the nodes A and B. In thiscase, the connections between the sensor device battery 140 and thenodes A and B may be cut off.

When the second group of control signals CN3 and CN4 are activatedduring the measurement operation, a measurement path may be formed suchthat measurement current flows to the healthcare controller 130 throughthe biosignal measuring sensors 111 and 112, the nodes A and B, and thesensor selecting device 123.

The sensor selecting device 123 may include switching elements T3 andT4. Here, the switching element T3 may be connected between the node Aand the healthcare controller 130, so that the switching operation maybe controlled in response to the control signal CN3. In addition, theswitching element T4 may be connected between the node B and thehealthcare controller 130, so that the switching operation may becontrolled in response to the control signal CN4.

In an embodiment of the present disclosure, the switching elements T1 toT4 may be implemented with NPN type bipolar junction transistors (BJTs).According to another embodiment, the switching elements T1 to T4 may beimplemented with PNP type bipolar junction transistors.

Embodiments of the present disclosure are not limited thereto, and theswitching elements T1 to T4 may be implemented with field effecttransistors (EFTs). A field effect transistor may include three devicesincluding a source, a drain, and a gate, and it is possible to controlthe current of the source and the drain by using a principle in which avoltage is applied to a gate electrode, creating a gateway through whichelectrons flow by an electric field of a channel.

As described above, the selecting device 120 may connect the biosignalmeasuring sensors 111 and 112 to the healthcare controller 130 or thesensor device battery 140 according to the switching operations of theswitching elements T1 to T4.

Table 1 below shows a state in which each of the switching elements T1to T4 is turned on or turned off according to the potential differencebetween the nodes A and B during the charging operation or measurementoperation.

TABLE 1 Potential difference CASE between Nodes A and B T1 T2 T3 T4Charging 5 V or more ON ON OFF OFF Measurement Less than 5 V OFF OFF ONON Charging OFF OFF OFF OFF completion

Referring to Table 1 above, the voltage controller 121 may detect apotential difference between the biosignal measuring sensors 111 and112, that is, the potential difference between the nodes A and B, as alarge potential difference above a specific voltage during the chargingoperation. The voltage controller 121 may activate the first group ofcontrol signals CN1 and CN2 when the potential difference between thenodes A and B is detected above the specific voltage.

When the potential difference between the nodes A and B is equal to orgreater than the specific voltage (5 V) during the charging operation,the switching elements T1 and T2 may be turned on and the switchingelements T3 and T4 may be turned off in accordance with the first groupof control signals CN1 and CN2. Then, it can be seen that the sensordevice battery 140 is connected to the biosignal measuring sensors 111and 112.

On the other hand, the voltage controller 121 may detect the potentialdifference between the biosignal measuring sensors 111 and 112, that is,the potential difference between the nodes A and B, as a fine potentialdifference less than the specific voltage when the charging operation isnot performed. The voltage controller 121 may activate the second groupof control signals CN3 and CN4 when the potential difference between thenodes A and B is detected to be less than the specific voltage.

Accordingly, when the potential difference between the nodes A and B isless than the specific voltage (5 V) during the measurement operation,the switching elements T3 and T4 may be turned on and the switchingelements T1 and T2 may be turned off in accordance with the second groupof control signals CN3 and CN4. Then, it can be seen that the healthcarecontroller 130 is connected to the biosignal measuring sensors 111 and112.

In addition, when charging of the sensor device battery 140 iscompleted, the voltage controller 121 may deactivate all of the controlsignals CN1 to CN4. Then, all the switching elements T1 to T4 may beturned off. Accordingly, the connections between the nodes A and B, thesensor device battery 140, and the healthcare controller 130 may be cutoff, thereby reducing current consumption.
